I’m no expert here, but I feel like an object doesn’t cause problems, people do, and that removing the object only differs issues elsewhere. Wouldn’t a collaborative problem-solving approach be more helpful in the long term for all children, specifically if the issues are fighting, sharing, and playing at inappropriate times? And teach actual skills rather than just remove objects, which will only eventually be replaced by another fad. I often feel like these kinds of policies are just going in endless circles around the real issue, in an attempt to set the issue aside for later rather than ever confront it at all.
My response to this letter would be explaining just that. That’s just me though, and likely why my school would never dare send a letter like this with my children,
